TUSTIN HANGAR INCIDENT
Daily Incident Update
Date: 11/21/2023
Information Hotline: 714-426-2444
Hours: 7:00 a.m. — 7:00 p.m.
Email: hangarincident(c-r�,tustinca.org
Incident Website: h!Ms://tustinca.org
Start Date: Tuesday, November 7, 2023
WEATHER: The high winds Tustin has experienced over the last two days began slowly dying down around
2:00 this afternoon. Tonight, southwest winds are expected to be light at 5 to 10 mph, with gusts up to 20 mph.
Air monitoring and sampling stations have been placed at thirty-three locations around the hangar site and
throughout the surrounding communities. These stations constantly monitor the air for pollutants. If any
abnormal readings are detected, that information is sent in real-time to the Incident Management Team
Environmental Group. Water trucks are on constant patrol around the hangar and grounds performing dust
abatement.
BULK DEBRIS CLEANUP MAP: A public information map is available that depicts bulk debris collection
areas near the incident site and will be updated regularly. This enables community members to follow the
crew's progress in clearing the streets and right of way areas around the hangar site. Since cleanup crews were
unable to work on Monday due to the high winds, there is no update to the map for today. This should change
with tomorrow's map.
FIRE SUPRESSION / DECONSTRUCTION OF THE HANGAR: Work has resumed after the wind event
to extinguish all remaining hotspots of the hangar fire. Part of this effort involved the use of a drone with
infrared (IR) capability to identify hidden pockets of heat in the debris piles, and guide crews to saturate those
locations. A few remaining small areas of heat are being addressed, and we expect full extinguishment in the
next 24-48 hours. Currently, there is no visible fire or smoke from the hangar site. The remainder of the west -
facing wall has been fully deconstructed. At the present time, no action will be taken on the hangar doors or
concrete pillars, which will be addressed at a later date. A plan is being developed to stabilize the doors in place
for the safety of our workers and the public. The following bullet points outline the process and steps being
taken.
• Utilize heavy equipment excavators to remove debris to clear roadways to allow for water trucks to access
all areas of the hanger.
• Excavators will be used to create access to the heavy debris and deep seeded smoldering fires beneath.
• The excavator will remove all remaining hanging debris along both walls to allow safe access the structure.
• Water trucks equipped with nozzles and hoses will be used for dust abatement control throughout the
process.
• Water trucks will be staged on the far side of the hangar with continuous water saturation toward the
interior debris to further prevent further dust dispersion.
While the deconstruction continues, the OC Healthcare Agency (HCA) recommends that community members
follow the same air safety guidelines as previously released.

o Keep windows and doors closed.
o Remove shoes before entering the home.
o Turn on indoor air purifiers.
o Do NOT run your air conditioning units, HVAC systems, swamp coolers, and/or whole house fans off to
minimize drawing outside air inside your residence.
o If you have a pet, minimize outdoor activity.
o To further reduce any exposure during the winds, close your fireplace damper and ventilation fans.
To reduce your exposure outdoors:
o Avoid touching debris.
o If your skin, eyes, or mouth inadvertently encounter debris, wash thoroughly as soon as you can.
o Avoid activities that will displace debris related to the fire. (Avoid sweeping, landscaping, leaf blowing,
mowing, gardening, etc.)
o Avoid outdoor activities, minimize contact with your yard furniture and play equipment.
o Avoid temporarily closed areas (parks, schools).
o If you go outside in the immediate area, keep it brief. The use of a disposable P-100 or N-95 mask can
offer some protection.
o Seek medical attention if you have any medical concerns.
AIR MONITORING INFORMATION: Air monitoring and sampling locations have been set up surrounding
the North Hangar Fire incident to provide the Incident Management Team real-time information on Particulate
Matter (PM) in the air. While the units are in place, a graph showing the average reading for the last 24 hours
has been provided for the public's reference. This graph can be accessed from the Hangar Incident website
located at https://tustinca.org. Any questions regarding these numbers should be directed to the Tustin Incident
call center at 714-426-2444. The Incident Management Team Environmental Group is monitoring the air
quality around the incident for any ratings above 154 micrograms per cubic meter (mg/m3), which may cause
individuals in sensitive groups to experience adverse health effects. This is a moderate threshold that is less
likely to affect the general public. "Particulate matter," also known as particle pollution or PM, is a complex
mixture of extremely small particles and liquid droplets that exists in the environment including pollen, dust,
and soil. For more information about air quality and monitoring, visit the AirNow website at www.aimow.gov.
